China Marine Projection Magnetic Compass

Type CGY-165 projection magnetic compass
Type CGY-165 projection magnetic compass is specially suitable for various kinds of large and medium merchant ships and naval service vessels to indicate the heading and determine the azimuth. With the help of an excellant optical projecion sysem, the operator can easily and precisely observe the ship's heading in whelhouse.
CGY-165 projection magnetic compass can be conveniently mounted on the compass desk (the top of wheelhouse), the optical cylinder with the binnacle can stretchinto the wheelhouse through the base of binnacle. Partial image of the car of compass bowl can be displayed on the plane mirror atthe end of the opticl cylinder.
This compass is designed to meet the technical requirements of GB/T14108-93 and ISO-449 standards reerring Class A magnetic compass.
